Following the recent upgrading of the Alfa Laval PureBallast 3 type-approval by the USCG and the application by the company for USCG type approval for its 3.2 PureBallast variant – which already has IMO revised G8 approval, more applications from other makers have been received by both USCG and the IMO.

The USCG has advised that the EcoBallast Ballast Water Management System manufactured by Hyundai Heavy Industries is the 24th system to have an application for type-approval lodged. The system is a filtration and UV type.

Meanwhile a number of systems have applied for various approvals at the IMO’s MEPC 74 meeting taking place in London next month.

The meeting will receive details of the type-approval granted to the Desmi CompactClean UV system granted under the revised G8 procedure and consider applications for basic and final approval of several systems under the G9 process.

Applying for Basic Approval are the CleanBallast system from RWO and the FlowSafe system from Cyprus. The CleanBallast approval application is for an updated version of the system produced by RWO and in this second generation version renamed CleanBallast - Ocean Barrier System an updated electrochlorination cell using a higher dose of active substance is incorporated.

The FlowSafe system is a newcomer announced only recently and The FlowSafe ballast water management system (BWMS) uses a combination of two methods for treatment, SeaWater Conditioning Unit (SWCU or Trident Unit) and electro-chlorination unit for killing organisms by destroying the genetic materials. The SWCU is installed in line with the main ballast stream. The electro-chlorination unit produces sodium hypochlorite in a side stream and stored in a storage tank. Sodium hypochlorite is subsequently injected to the main ballast line. Sodium thiosulphate will be injected as neutralisation agent upon deballasting as needed.

Applying for final approval under the G9 process are Envirocleanse’ InTank, system, Kuraray’s Microfade II, Samsung’s Purimar system – which already has approval for sea- and brackish water – for use in freshwater and finally JFE’s BallastAce system using NEO-CHLOR MARINE.
